Application led October 27, 1917. Serial No. 198,791.

T 0 all whom z''mag/ concern.'

Be it known that l, HERMAN E. HurriurLLuR, a citizen of the United States, resi- A further object is to provide a tongue truck which will allow for the vertical oscillation of the axle and the up and down movement of the wheels in passing overl rough or uneven ground.

A further object is to provide a truck of simple construction and one which will not tilt or become cramped in turning.

Other objects of the invention will appear from the following detailed description.

In the accompanying drawings formingl part of this specification,

Figure 1 is a plan view of a tongue truck embodying my invention,

Fig. 2 is a sectional view, showing the manner of mounting the truck on the axle and the bearings of the stub tongue on the truck.

In the drawing, 2 represents the axle having suitable carrying wheels 3. 4 is an upright standard. having a forked lower end 5 pivoted at 6 on the axle. The upper end of this standard has a spindle 7 seated in a bearing 8 in the stub tongue 9 to which thc binder is connected in the usual way. A hub 10 is mounted on the standard 4 beneath the tongue 9 and is provided with a spiral groove 11 in the surface thereof. This huh is securely fastened on the standard. 1'2 is a brace secured atY one end to the underside of the stub tongue and projecting downwardly and forwardly therefrom and forming a guide and bearing for the standard 4 and also for the lower end of a holt 13. the upper portion of which is seated within a bearing 1l in the forward end of the tongue 9. A casting 15 is mounted on the bolt 13 between the brace 12 and the underside of the tongue 9 and has a wheelY 16 formed thereon provided with luge 17 to which the ends of chains or othertiexible connections 18 are attached. These chains'are carried back to the hub 10 and fitted 'within the groove 11 and secured therein, so that when the wheel 16 is rocked back and forthV in a horizontal plane, a

strain will be alternately applied to the chain Y18 to rock the spindle 4 on a vertical axisand oscillate the axle to change the angular position of the wheels 'with respect to the stub tongue. The casting lfhas a. socket 19 therein'in which a tongue 20v is secured by a bolt 21, said bolt forming a horizontal axis for the tongue 20, allowing it to be rocked up or Vdown and permitting the wheels to drop into depressionsV or in' f equalities in the ground without undue strain or pull on the neck yoke. The hub 10 and the wheel 16 may be made in dif-V ferent sizes and in various ways the details of construction herein shown and described may be modified and still be within the `scope of my invention.

I claim as my invention:l 1.` A tongue truck comprislng an axle and wheels therefor, an upright standard mounted on said axle, a stub tongue having a bearing for the upper end of said standard, a hub secured on said standard, a

Vwheel mounted on said stub tongue in adnaled on said `stub tongue in front of and i adjacent to said hub., chains attacher"L to the periphery 'of said wheel and having their rear portions fitting within said groove and secured thereto,V whereby the rocking of said wheel laterally will imparta vrotating i movement to said hub and axle, and a draft tongue mountediin said wheel. y

B. A tongue truck comprising an axle andl wheels therefona standard mounted yon said en of said standard,a hub secured on said axle., a stub tongue mounted onthe upper eral rocking` movement of said casting will standard; a'casting'mounted on sadstub tongue 1n advance of sald hub andhavl'ng curved. peripheral surfaces,v flexible: means Y attached to sald curved perlpheral surfaces -fon opposlte sldes thereof and Wound on said hub, and secured thereto, whereby latrotate said hubv andy standard, andadra'ft tongue mounted in sald castmg.
